Hardy's injury is a serious blow both to the shortstop, who finally felt healthy again, and the Orioles' lineup which benefitted greatly from having a threat in the No.9 spot. If there is any positive that comes from the injury, it will give the Orioles the option of bringing up a true back-up catcher in Craig Tatum and allow Jake Fox to be used more in a utility role. For now, the Orioles will use the extra roster spot to add another bullpen arm and Tatum will remain at Triple-A Norfolk. However, if some of the younger pitchers start getting deeper in the game, it won't be long before Tatum joins the club. It was clear on Saturday night that Jake Arrieta and Fox weren't totally in sync, which is understandable considering they haven't worked together much. One head-scratching sequence came in the Texas Rangers' six-run third inning against Arrieta. With runners on first and third and no outs and the Orioles leading 1-0, Arrieta fell behind No.9 hitter Mitch Moreland 3-0. He proceeded to throw back-to-back offspeed pitches on 3-1 and 3-2, issuing a walk. Moreland is a good-looking young hitter, but with the dangerous Ian Kinsler on deck and the Rangers' vaunted lineup turning over, you absolutely have to challenge Moreland with the fastball in that situation. Now, the responsibility – and the blame in this case - doesn't fall all on Fox's shoulder. Arrieta has the ball and ultimately could shake the catcher off and get the sign that he wants. I assume that was one of the things that manager Buck Showalter was telling them during that long conversation that TV cameras picked up later in that game.Showalter's comment later that Arrieta had too good stuff to have an outcome like that probably alluded to several things, including Fox's game calling Either way, Fox is a valuable player to have on the roster, but that value is with his ability to play multiple positions and bring a power bat off the bench. It's not behind the plate.
